Bio-Control Monitoring

Monitoring biological control agents is an essential component of a successful biological control program. Capturing this data helps us accurately document the impact of this weed management practice. This has been endorsed by the Nez Perce Biocontrol Center, University of Idaho, Forest Health Protection, Bureau of Land Management, and Idaho State Department of Agriculture.

The data captured is used to document vegetation cover, target weed density, and biological control agent abundance. When conducted annually, this monitoring data will document changes that occur over time.

The monitoring form is designed to accompany all of the permanent monitoring systems and pre-release monitoring systems listed below.
